ALFRED J. SODEN, OF NEWARK, NEW J PROJECTILE.

Specification of Letters Patent.

Patented Dec. 22, 1914.

Application filed February 12, 1918. Serial No. 747,843.

Be it known that L'ALF-RED J. SODEN, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Projectiles, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will. enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to figures of reference marked thereon, which form a part of this specification. v v

This invention relates to an improved means for fastening. caps on the pointed ends of projectiles, by means of which the cap is permanently attached to the pointed end of the projectile and the connection between the shell and the cap is substantially covered.

The invention consists of a shell and a cap so secured that the cap can be turned on its surface after it is attached, the conmotion between them insuring their rotation together when they are subjectedto the turning operation.

The invention is in the class of inventions shown and described in my Patent No..

918,923, issued April 20, 1909, being an improvement on the device shown in said patout.

The invention is illustrated in the accompanyin drawing, in which Figure 1' is a side view 0 a projectile with a cap attached, be-

ing broken away to illustrate the attaching means. Fig. 2 is an enlarged detail to more fully show the attaching means, and Fig. 3

is a section through Fig. 2, showing a ring and pin in elevation, the ring and pin being part of the attaching means.

I illustrate a projectile 10 with a pointed end 11,.the pointed end having agroove12 which is set back a short distance from the point. Fitting in the groove 12 is a bead 13 on the inner face of a split ring 14, the ring being split'so that it can be sprung in the groove. A cap 15 is hollowed so that it fits a ainst the point of the shell and 1S provi ed with a screw-threaded portion 16 which is screwed on the threaded portion 17 -of the splitting. The cap has spannerholes18 by means of which it can be screwed on the shell, the spanner-holes being so disposed that they are over the threads 17 when the cap is in place, this permitting the mutilation of the threads 17 to permanently secure the cap against rotation on the rin'g. The cap 15 has an apron 19 extending beyond the ring 14 and engaging the shell in rear of the ring, thus substantially covering the ring and preventing the exposing of the split portion to the action of rust and also preventing the split in the ring being on the exterior to form an air pocket and thus affect the accuracy of the projectile.-

I have found it desirable under some circumstances to put the cap in place as above described and then turn down the outside of the cap by placing both shell and cap in a lathe or the like and then subjecting the cap to the action of the proper tools. Thiswill sometimes cause the ring to slide around in its groove and turning can not be accomplished. To overcome this, I provide the pointed end 11 of the shell with a hole 20, and I provide the ring 14: with a recess 21, the hole and recess being preferably in the line of the groove 12because the ring has more body to it where the bead 13 is. A pin 22 is placed in the hole and projects into the my invention, what I claim 1s:

1. The combination of a shell having a" I pointed end and having an annular groove therein, a ring fitting in the groove, the shell having a hole therein, the ring having a recess therein, a pin extending into the hole and into the recess, a cap bearing on the pointed endpf the shell, and an operative connection between the ring and the cap to force the ring in the groove.

2. A shell having a pointed end with a groove therein and also having an opening.

on the pointed portion, a ring adapted to be placed 1D. the groove, the ring having a re cessed portion on its inner face, a locking element placed in the openingin the shell and having the-recessed portion of the ring fitting over and holding the locking element in p%sition, a cap fitting on the end of the -sh and having a screw-threaded "connection with the outer face of the ring,

and means for locking, said connection against rotation when the cap is in place.

3. A shell having a pointed end with a groove therein and also having an opening on the'pointed portion, a ring adapted to be placed in the groove, the rin having a recessed portion on its inner ace, alocking element placed in the opening in the shell and having the'reeessed portion of the ring fitting over and holding the locking element in position, and a cap fitting on' the endof the shell and held on the ring to prevent any rotation relative to each other.

In testimony, that I claim the fore oing, 15

I have hereunto set my hand this 7th ay of February, 1913. g
